The present invention discloses a device for monitoring chemotaxis or chemoinvasion. The present invention further provides a flexible assay system and numerous assays that can be used to test biological interactions and systems. Laminar flow gradients are employed that mimic gradient situations present in vivo.
摘要:
The present invention discloses a transgenic fly that expresses a carboxy terminal fragment of the human amyloid-β precursor protein (APP) and a double transgenic fly that expresses both the fragment of APP and tau protein. The transgenic flies of the present invention provide for models of neurodegenerative disorders, such as Alzheimer's disease. The invention further discloses methods for identifying genetic modifiers, as well as screening methods to identify therapeutic compounds to treat neurodegenerative disorders using the transgenic flies.

A digital growth plotter according to the present invention includes a housing for being conveniently and ergonomically held by a caregiver. The growth plotter includes a processor, input devices, a data storage device, and a display. The housing may include a battery for energizing the electronic components. The input device may include a keypad and touch screen for efficient user entry of growth information, said growth information being stored in the digital storage device. The processor includes programming for downloading an up-to-date growth chart for comparison with recorded growth information. The processor also includes programming for plotting a growth chart according to the recorded and standard growth information. Then, the processor may upload the recorded information to a compiling entity so that the standard chart may be updated/revised for more accurate comparisons and analysis in the future.
摘要:
Media, kits, and methods are disclosed for use in processes requiring microbial culture. More specifically, the invention provides carrageenan-stabilized agar-based microbial culture media for kits and methods. The media and kits of the invention possess increased shelf-life stability over currently available agar-based media. Further, the media, kits, and methods are useful in the manual determination of identification and antimicrobial susceptibility testing of the pathogen/s contained in a specimen or sample in periods of about 12 to 24 hours. The stabilized culture media of the invention are useful in a broad variety of applications.
摘要:
An image analysis system for automated reading of printed multi-character codes, for example on antibiotic susceptibility testing disks, makes use of an orientation means, for example an underline printed beneath the code, to bring the code or its image into canonical alignment with an optimum reading direction for the code. Automated reading of the codes on randomly-orientated AST disks is therefore possible.
摘要:
Single or multiple blood plasma component concentrations are measured by a disposable stick having one or more blood plasma component reactive areas covered by a semipermeable membrane which is permeable by blood plasma or serum components and impermeable by blood cellular and particulate matter. A second overlay may be superposed with the semipermeable membrane over the reactive areas to receive a blood sample and meter and distribute that sample uniformly to the semipermeable membrane which in turn passes the plasma components uniformly to the reactive areas. The overlays are subsequently separable from the reactive area to remove the cellular components and particulate matter and expose the reactive areas for inspection by, for example, color comparison to standardized charts.

摘要:
The present invention provides N-acylidihydroresorufin derivatives of the general formula: ##STR1## wherein R.sup.1 is a lower alkyl, aryl or aralkyl radical, which can be substituted by carboxyl or sulphonic acid residues, R.sup.2, R.sup.3 and R.sup.4, which can be the same or different, are hydrogen or halogen atoms or lower alkyl or lower alkoxy radicals, Y is an --NR.sup.5 R.sup.6 or --OR.sup.7 group, wherein R.sup.5 and R.sup.6 are, in each case, hydrogen atoms or lower alkyl radicals, which can be substituted by carboxyl or sulphonic acid residues, or together represent a hydrocarbon bridge optionally interrupted by hereto atoms and R.sup.7 is a lower alkyl radical which can be substituted by a lower alkoxy or poly-lower alkoxy radical.
摘要:
A method for screening bacteria to select strains which will suppress diseases caused by the fungus Gaeumannomyces graminis (Gg) under field conditions and a method for applying field-suppressive bacteria to suppress Gg in a commercial setting. Four fluorescens Pseudomonas strains are disclosed which are effective in suppressing take-all in wheat.
